SHOCK GATHEREB.

Application filed April 10, 1919. Serial No. 289,080.

I '0 all whom it may concern:

Be it known that I, Cnnnnns PEARSON, a. citizen of the United States. residing at Chicago, in the county ot Cook and State of Illinois, have invented certain new and useful Improvements in Shock Gatherers, of which the following is a full, clear, and exact specification.

This invention relates to machines for gathering and transporting shocks of grain or other material,

The invention has among its objects to facilitate the gathering and transporting of shocks of grain and to provide a construction having a maximum capacity for the size of the structure, and moreover, a construction that may be operated by power.

A further object is to provide power operated connections for tilting, raising and lowering the gathering means and also to control these power connections in such a manner that the gathering means may be tilted to various angles, and also in such a manner that the rear end of the gathering means may be raised oil the ground while the front end is maintained substantially in contact with the ground.

A still further object is to provide supporting and steering means for a device of the character described, this supporting and steering means being so mounted that the said means will not be thrown out of control when the n'lachine is started either forwardly or rearwurdly.

With tl'ies-o and othcr objects in view. which will appear as the description proceeds, l have embodied my invention in a practical construction which has been illustrated in the accompanying drawings. and in these drawings,-

My improved shock gatherer consists, briefly. of araking member having longi tudiually extending lines. the frame of this raking member boingvertically adjustable upon a carrying. frame. The mixing member frame is supported upon two carrying wheels and a power shaft is operatively connected to one of the carrying wheels. This power shaft is provided with suitable clutch mechanism and a plurality of pinions, the

inioI-is meshing. with vertical racks carried iiy the frame of the raking member and operating; to raise and lower the racks and the frame of the raking member as the clutch mechanism is operated to connect the power shaft with the drivingawheel. Lever mechanism is also carried by the supporting frame and is connected to the rake frame in such a manner that the rake may be tilted to the desired angle. The supporting frame for the raking member is provided with a rearwardly extending pole, the rear end of which is supported upon a steering wheel and provided with a vertically extending shaft by means of which the wheel support may be rotated on a vertical axis anxlithe shock gatherer may be steered. The construction last referred to is similar to that. found upon headers and sweep rakes.

Referring now to the drawings. the supporting frame for the rake frame includes a longitudinal pole. member 30 having), a bracket 31 secured to its rear end. this bracket heiuyr provided with spaced lugs in which journaled a vertical shaft. 33 having an upper squared portion 34. The portion 3-} of lhc shaft 323 has iuoiurtcd thereon a. brarliet 35 which carries a forwardly projecting handle 37, having a seat 36 mount-ed thereon. this construction being similar to that found on headers. as above stated.

The rear end of the pipe or pole member S30 is supported by means of a supporting and steering. wheel 38 pivotally mounted on an axis-39-carried by U-shaped bracket 40. The bracket 40 is pivoted on a horizontal pivot pin 41 carried-at the lower end of a ln 'arlret 4.9..which is mounted onthe shaft 33. as clearly illustrated in Fig. 5. The U- shaped bracket 40 has formed thereon a bridge portion iftwl rieh is disposedintermediate the. rim of the wheel and the pivot -41. and is adapted to contact with downwe. 'dly extending spacedrlugs r-formed on the lower end of the bracket 42'.

ln Fig. 5 the steering wheel 38 and bracket 40 are shown in the position which they assume after the machine has-been started and is being propelled around the field. \Vhen it becomes necessary for any reason to baclt the machine, the wheel 38 and bracket 40 Willzbe moved to the position shown in dotted lines in Fig. 8, the bracket 40 swinging on the pivot 41. It will be readily understood that as the machine is backed there will be a tendency for the wheel 38 to move. either on the vertical pivot or upon its horizontal pivot 41, and in the absence of the pivotal connection between the bracket: 40 and the bracket 42, the wheel 38 will be swung on the vertical pivot and the driver,-unless special care were taleen would be tin-own from the seat.

In my construction, however, the pivotlIYgUf the bracket Mien the pin 41 prevents the rotation of the wheel 38 on the vertical pivot, since this initial movement is taken up by swinging'the wheel to the dotted line position shown in Fig. 8.

The construction just described operates inan exactly similar manner when the machine has been hacked and is started forward again.

The front end of the pipe 30 has secured thereto a pair of brace members -15 secured at their inner ends to the pipe and divergingfor a certain distance each side of the pipe. the outer ends of these members being bent forwardly and disposed in parallel relation as shown at 46. The IM riioi1s -tG-of the brace members L55 are connected by means of a transverse frame member 41'. and the front ends of the portions it are connected to the pipe. 30 by means of additional brace members 48 these members being connected to the transverse member T by brackets 49. The front er-Ml oft-he pipe 30 has secured thereto forwardly extendingbracliiets or framr mom-Law's. to. which carry at their front ends vertical brackets 51 provided with horizontal journal through which extends the litfid tl' fillll'l i. 5:15. Vertical brackets 53 are also secured to the front ends of the portions 46 of the brace memhere. 45. and these brackets are alsoprovided with horizontal journals which support the shaft 52.

The shaft 52 is supported at its outer ends .L

loo

llll

vertically extending members 58, a'series of these members being secured at their lower ends to the front transverse frame member 56 as shown in Fig. 2. A plurality of horizontal frame members 59 are employed to strengthen the verti val frame. and these members are secured at their opposite ends to certain of the vertical frame members 58, this construction being also shown in Fig. 2. Diagonal braces 60 are provided to strengthen the rake frame, these members extending between the horizontal and vertical frame members and being secured at their upper ends to inclined frame members 61, which are carried by the vertical members 58 at their upper ends, a bracket 6:! connecting the members 61 at their upper ends.

A plurality of longitudinally extending rake lines 63 are secured to the horizontal frame members 56, preferably by means of U-shaped bolts 64%. The main portion of the rake is mounted between the carrying wheels, but in addition to this portion I have provided a supplemental foldin section outside of each of the carrying whee s.

The construction of these folding sections of the rake is illustrated in Figs. 1, 2 and 3, each section including transverse members 65 connected by diagonal braces 66, and having forwardly extending tines 67 mo actly similar to the tines 63. Inclined frame members 68 and 69 are pivoted at their lower ends to the outer ends of the frame members 65 as shown at 70, and have their upper ends rigidly connected together by means of a plate 71. A transverse bolt 72 extends through the upper ends of the members 68 and 69 and pivotally connects them to a guiding member T 3 which is provided with an angular slot 74 that fits over the upper frame member 61 of the rake frame as shown in Figs. 27 and 28.

The frame members 68 and 69 have pivotally secured thereto at their upper ends a bracket 75 which is connected bv means of a cable T6 extending over an idler T7 to a winding drum T8 fixed to the power shaft :32, and as the shaft rotated the cable 76 will be wound on the drum and the supplemental rake frame members will be folded as shown in Fig. 3. If desired. a clutch may be interposed between drum T8 and shaft 52 to enable the operator to disconnect the drum from the shaft at will. The inclined frame member 69 of the supplemental rake frame has secured to its lower end a bracket 78 which supports a supplemental rake tine T9. the rear end o l which is bent downwardly and secured to the diagonally positioned member 68 as shown in Figs. 2 and 3. This supplemental tine retains the bundles on the sup ')lemcntal rake frame. Hooks 80 are carried at the upper ends of the outer vertical frame members 5% and cooperate with eye-bolts 81 to hold the supplemental rake frames in their extreme folded position for transport, as shown in Fig. 2. It will be understood that, in the particular construction illustrated. as the rake frame is raised by means of the power derived from the shaft 52 and the cables 76 are wound on the drums carried by said shaft, the supplemental rake frames are folded only to the position shown in Fig. 3, and that the sup plemental rake frames are folded to the extreme folded position shown in Fig. 2 only for transport. said supplemental frames being manually lifted to that position. However, by simply changingthc size of drum T8 the supplemental frames may be completely folded by the power shaft and drum. Shield members are secured in any suitable manner to the supporting frame and extend around the front of the carrying wheels 54 thereby preventing any hay or grain from coming in contact with the carrying wheels.

The drivihg connections and the: clutch mechanism between the power shaft and the driving wheels will be next described.

As illustrated in the drawings, a single driving wheel is connected to the power shaft, but if desired both wheels may be so connected.

Turning now to Figs. 9 to 20, the clutch mechanism will be explained. As shown in Fig. 9, the hub 83 of one of the wheels 54 has secured thereto or formed integrally therewith, a constantly rotating clutch member 84, having an outwardly extending annular flange portion 85. The portion 85 of the constantly rotating clutch member 84 has formed thereon inwardly extending lugs 86 adapted to be engaged by roller-s 8? rot-atably mounted in triangular shaped pawl members 88 pivoted at 89 to outwardly projecting apertured lugs 90 carried by a sleeve member 9! which is keyed to the power shaft 52. This construction is illustrated in detail in Figs. 9, 12, and 13.

The particular construction of the pawls HR is illustrated in Figs. H and l5 and from said figures it will be seen that. the pawls, as above stated, are triangular in outline, outwardly extending lugs 90 being formed thereon, springs 91' engaging the lugs 90' and recesses 92 formed in the pawl supporting sleeves 91. The pawls are also provided with laterally extending or offset lugs 93 which engage notches 94 formed in the outer ends of a pawl controlling bracket 95 journaled on an extension 96 of the sleeve 91 which forms the support for the pawls. The pawl cont-rolling member 95 has formed integrally therewith a wheeled member 97 having a series of peripheral notches 98, this notched wheel forming a ratchet wheel. The springs 91 above referred to tend to swing the pawls 88 about their pivots 89 to the position shown in Fig. 12, in which position the rollers 87 are out of engagement with the ings 86 carried by the constantly rotating mem'her 34.

The method of manipulating the pawl controlling member 95 and the mtehet wheel 91' will next he described.

A pawl 99 is'securod to a elntoh'shaift 100 carried by one of the frame members 50 and a portion 46 of one of the frame members 45. A spring 101 is secured 35b one end to an upwardly projecting lug 102 formed integral with the pawl. and at its opposite end to a portion of the main sup porting frame. this spring operating to hold the pawl 9t) in engagement with one of the;

notches 98 of the ratchet Wheel 97. as illus trated in Fig. 12 The engagement of the pawl 99 with the ratchet Wheel prevents the rotation of the ratchet wheel and ottlte pawl controlling'm-emher 95 formed integral therewith.

in Figs. 11 and 16 I have shown :1 supplementsl pawl 103' pivotolly mounted at 1H4 on the pawl 99. the pawllOS htrv'ingn forwardly projecting tooth 105 adapted to engage the note-hes 99 of the ratchet wheel 97. As stated above. the springs 91' nor mally hold the pa wls in such a position that the rollers 87 are outof engagement. with the: lugs 86 carried by the constantly" rotating clutch and therefore the power shaft 5:2 is not driven by the carrying wheel When the operator desires to positively connectthe power sheft to the driving wheel to raise or t-iltthe rake fisrme; he presses downward-l3 on a foot trendle 106 which is connected by means of a link 10? to an airm 107' eerried liy the clutch shztft 100 which carries the pawl 99. This operation raises the pawl 95), see Figs. 3. ll. 21 and 22: out of engagement with the ratchet Wheel 97 ire-ting against, the spring Ed and at the some time the pawl 1H3 drops into eun'mggetneut with one oi the notches of the ratchet Wheel and rolntes the. ratchet wheel through-a smailamg'le in an anti-clockwise diret'tiorr (Viewing Figs. ll to i This rotation oi the ratchet wlteel also causes a similar rotation in the more direction (it thepawl controlling: member 9'5 and the rotatitm ot" tll'is trieitrlfier by its engagement with the otl'set lugs 93 carried l fe" the pawls 88. moves the'pewls on their pivots S9 in an anti clockwise' direetion. so that the rollers 87 will engage with the lugs 86 carried by the constantly rotating clutch member. A t'ter the rollers are in engagement with the lugs there is sutiieient triction to retain them in engsgenrentun'til they are withdrawn from engagement when it is desired to disconnect the power shaft from the driving wheel. This disconnection is made in the following. manner: After the. reek frame has been raised to the desired altitude. the operator releases the pawl 99 which then dr '8 into engagement with the ratchet wheel 9 and as this ratchet wheel is engaged by the pawl, the further rotetion of the ratchet Wheel is prevented and the pewls nrengain swung about, theirpivotsS-l, this time in at clockwise direction, out, of engagement to a. position in which the rollers 87 are out of engagement with the lugs 86. After they have been drawn from this engagement, the springs 91' hold them in the position shown in Fig. 12. or in inoperative position.

In order to prevent injury to the machine and to automatically throw the power con nections out oi operation in ease the open 5 utor forgets to remove his foot from the foot trezulle. additional means has been provided to automatically disconnect the power shaft from the driving wheel. This means is illustrated in Fig; 11 and consists of :1 pawl I08 pivotelh connected at 109 to the rake mine and disposed in a position to engage the ratchet Wheel 97 when the rake frame has reached its upper limit of position. The rear end of the pawl 108 is shit-ted as shown at l 11). a pin lll extending throngh the slot and being secured to the mke tra inegtliis pin and slot. living provided to limit the movement of the pawl about its pivot. As illustrated in Fig. 11. the rear end of the pawl is heavier than the front end and the pawl therefore is normally disposed in the position shown in said figure. The eetion of the pawl 1H8 is exactly similar to that, of the pawl .59 and the same results are 01* mined. and it is not; bel'ievedto be necessary to explain" this station in detail.

The connections between thee power sho'ft and the rake frame whereby therslte traime is raised and lmrered; willnext he, described.

As shown in Figs. 2 and 3. the rake frame has secured thereto a pln rniity oi rertieul ruck members 112. these members being spaced across the width of the Frame. l laelt of these ruck: members eonsists of two reeks it? and lli. the teeth of the two rim-ks being disposed in ste grereril relation as clearly illustrated in To cooperate with these rocks in 1111 no and lowering; the

trzune. l have secured to the power shaft filllllltlllty of pairs u'l pinion e 11:3 mid H6. the teeth on these pinions also being: disposed in staggered relation as shown in l 9 and it), and being adapted to engage the respective racks 113 and 114; The object of this particular form of ruek and pinion is to provide greater strength. since in this way twice the amount of engagement between the racks and pinions is obtained over what, would he obtained it a single rack and 'sinion were utilized. Referring to Fig. 26. i will also be seen that the douhle rock and pinion construction maintains the rake frame against lateral displacement. The

racks being tightly secured to the rake frame as illustrated in Fig. 11, and the pinions being rigidly secured to the shaft 52, it will be seen that as the shaft is rotated the rake frame will be positively raised and lowered. Having described the connections for raising and lowering the rake frame, the means for retaining the rake frame in raised position and for retarding its descent, will next be described. This construction is illustrated'more particularly in Figs. 21 to 25.

The means for retaining therack in any desired position of elevation comprises a ratchet wheel 117 secured to the shaft 52 and having a series of teeth 11S adapted to be engaged by a pawl 119 pivoted on a trans verse shaft 120 carried by the forwardly projecting frame members 50. A spring 121 engages the frame of the machine at one end band 123 secured at one en operator on the seat 36 by and at its opposite end engagesthe pawl 119 and holds the pawl in engagement with the ratchet wheel. As the frame of the rack, therefore, is raised, the ratchet wheel is engaged by the pawl 119 and prevented from backward or reverse rotation, and in this way the rake is retained in any adjusted position. The pawl 119 is controlled by the means of a connecting rod 119 to a foot treadle 119".

The shaft 52 also has secured thereto a brake drum 122 which is en' god by a brake as shown at 124 to the transverse shaft 120, and having its opposite end connected by means of a bolt 125 to :1 laterally offset portion 126 formed integral with the pawl 119. From this arral e-ment itwill be seen that a single means has een provided in which the ratchet pawl 119 through the connection 119 and foot treadle 119 releases the ratchet wheel 117 and at the same time applies the brake on the brake drum 122 through thebrake band 123 which is connected by the bolt 125 to the ratchet pawl 119.

From this description it will be seen that as the pawl 119 and its ofi'set portion 126 are rotated on the shaft 120 to release the ratchet wheel and therefore the power shaft' 52, in order to lower the rake frame, the

free end of the brake band 123 will be moved in such a direction as to tighten the brake band on the drum 122.. and cushion or retard the descent of the rake frame. A counterbalancing spring is lso utilized to assist in the raising of the rake frame and to also retard its descent, this spring being shown particularlvin Fig. 22, In this figure the counter-balancing spring 127 is adjust-ably connected at oneend to a downwardly extending bracket- 128 carried by the pole member 30, and; at its o posits end':

is connected to a cable 129. T e opposite end of this cable is wound upon a sleeve 130 secured to or formed integral with the ratchet w el. 11?, 2 38 the 911d f t is cable in Fig. 22 it will be seen that the spring.

is utilized to assist in rotating the ratchet wheel in an anti-clockwise direction to raise thoralre frame, and j-that this spring also retards the movement of the rake frame in the o posite direction, or retar s its descent.

Having described the raising and lowering mechanism for-the rake frame and'the controlling mea'ns therefor, I will next describe the means for tilting the rake frame. The object of tiltin'gthe rake frame is to increasethe capacity of the tines. As a series of shocks is gathered they. are forced by the forward movement of the-tines and the engagement of their butts with the stubble, to the rear ends of the tines to a'posi tion adjacent the vertical portions 58 of the rake frame. -In order to facilitate the gathering of a, second series of shocks be-' fore dumping the first series, it is. desirable that the butts of the shocks; first gathered,- or those shocks at" the rear ends f the tines,be raised to a position out of engagcment with the stubble, since the en'- gagement of the butts with the stubble retards the propulsion of the machine throu h the fieldand requires-a much greater drat; therefore. when the portion of the rake frame adjacent'the vertical frame members .68 has been loaded with shocks, the rear end of the-rake frame is raised to the interme-- diate dotted line position shown in Fig. 4..

Themethod oftil-ting the rake frameto this position and the construction b means of w iich-it is tilted, wi1l now be de ne'd.

The rake framehas secured thereto alaterally projecting lug' 131'- (SeeFig's. 4 and 26), and this log is engaged by the forward ends of chains 132 an 133. he chain 132 extends over a drum: 13 1 carriedf-by the shaft 52 and the chain 133 passes under the drum 134.1 The rear ends ofth'e chains areconnected to the front end of a link. 135

which is pivoted at its rear end to a lever the pipe," said "lever has ".pivotally connected therewith the front enr of a. link 138, the

'rea-r end of this link being pivoted at 139'to in other words,

thelowe'r end of alever 140, which is Pi otally' connected at 141 ;to' the pipe; In orde'rFto limit the forward movement of "the levcr about the pivot 141,1; bracket 142 is secured to the inpper portion of thef lever and is p'rovided'iit its lower end with'a stop member 143 adapted.- to' engage wi'th the pipe30 when'theieverl m is .moved about ri e n a nt -e eek r e ea. Theup'per' end, owf itlle. lever 1' 0 heSP YQiQQl the rake .to be tilte thereto one horizontal. pivot 1+1 1, sleeve 145 in which is journaled the rear end portion-ol s screw-threaded rod 1&6 which has secured to its rear end a hand wheel 14:1 The front end portion of the rod 1 16 is screw threaded and engages a screw threaded bracket 148 carried by the rear end of a pipe 149. Thewfront end ohthe pipe 149 is pivotally connected to a bracket 150 secured to the plate 62 which connects the up pertends-of .the inclined frame members 61. Thusit willhe seen that rod 116 .and pipe 149 form a connecting linkbetween lever 140and the rake frame.

Having described the construction of the tilting mechanism, the operation of this construction will .nowbe briefly set forth.

:Assuming that the operator has gathered aplnrality of shocks andtheseshocks are positioned at the rear ends of thetines 63, it thentbecomes desirable to raise the rear ends of the tines to the dotted line position shown. in Fig. 4, the front ends of the tines being still engaged with the ground. In order-to raise the rear ends of the tines to this position, the operator throws in the clutch which connects the shaft 52 to the drive wheelthereby actuating the pinions 11-5 and 116 endby .the engagement of these pin-ions with the racks 113 and 114:, raising the rake-frame. As the rake frame is raised, the lug'131 carryingthe front ends of the chains 132 and 133 will also be raised, but if the rake is raised only to the intermediate position shown in Fig. 4, the chain 133 will remain slack-and the front end ofthe chain 132 will extend .over the drum 13 1 as shown in Fig. 4, and will ermit the front end of downwardly. Therefore, the rear end of the rake alone will be raised. Iii otherv words, the'chain 133 controls the angularity of the tines 63 when the rake frame is in a raised position and the chain 132 controls the .angularity of the.

tines 63 when the frame is in a lowered position. In this connection it will also be noted that when the frame is raised from full line position to intermediate dotted line position shown in 1, the chain 132 becomes slack, releasing the tension of the rod 135. and through the connections 136, 138 and 140 the pipe 149 is permitted to move forwardly with the frame 58 into the forward dotted line position and thereby causing. the forward ends of the tines to engage the ground- It will be further noted from Fig. 2 that the cable 76 shown on t-he left hand side: is slack, thus permitting the rake frame proper to raise toflthe intermediate dotted line position shown in'llig. 4: before the extensionsstartto swing in assuming the positions shown inFig. 3. After the rake frame has been filled to capacity with shocks, .the operator again throws in the clutch {and raisesthemake flame to the upbeen raised into contact with the drum 13 1 and has become -taut,-thereby-exerting.a -forward pull on the link 135, lever 136, link 1158, and lower end ofthe lever 1&0. tilts the lever 140 about its pivot 1 11 and therefore pnlls rearwardly on the pipe 149,

tilting the upper end'of the rake frame rear wardly to ther-ight hand dotted line position (Fig. 1). In this position the rear end of the rake-is disposed in a .plane below-the front end of the rake thereby retaining the shocks in position on the rake tines. By means of the screw threaded adjustment between the rod 146 and the bracket 148, the amount oat tilting may be varied to suitt-he conditions.

Theoperations of the raising and lowering, tilting and steering .mechanismshave been set forth .in the-foregoing specification after the respective descriptions of these c onstructiens, end-therefore -a further statement regarding-the various operations is not believed .to be necessary.

From the above description of the construction of my improved shock gathering machineit will be seen that I have provided means .for gathering; a. plurality-of shocks ill) on tlie ralce frame, and means for raising the rear end of the rake frame to elevate these shocks out o.f--contact=with the stubble, after which a further number of shocks may be gathered to completely fill the-forward end of the rake frame. After the rake frame is thus filledto capacity with shocks, the frame may be raised and tilted upwardly at the front to retain .the shocks in position thereon. By means ot'. the construction described, theseoperetions may be carried out with a. minimum amount of-manual labor and the shocks may be gathered, transportedrand deposited incl con-i mretivelv short time and with great rapidity and efiiciency. The improved mounting for the steering and supporting wheel insures the proper 'steering of the device and also prevents the sudden turning of the wheelas the machine is started toi wardly or moved rearwardly.
